      <h1>Use Cases</h1>
      <p>There are two typical use cases for iTexx: </p>
      <ul>
        <li>1. iTexx as a tool for consolidating results in &quot;one shot web queries&quot;. </li>
        <li>2. iTexx as a retrieval companion working in parallel to your reading or writing activity. </li>
      </ul>
      <p>Yet, in everyday use there is no clear distinction between these two kinds of usage. Obviously, human work is <em>never</em> independent from a particular context. </p>
      <p>Such, the difference between the use cases is not so much a categorical one as it is a gradual one. The way you will use it will depend on the time that iTexx needs to do its job. The more focusing criteria you provide, the more &quot;intelligent&quot; the search has to be performed, the larger is the delay. Intelligence never comes for free, and intelligent retrieval of textual sources from remote places can't draw on statistical processes. </p>
      <p>Additionally, iTexx has to visit the primary results returned by the search engines <em>explicitly</em>. The consequence of that being that documents have to be downloaded. Nowadays, web pages are far more complex than they were back in 1995, mostly, there is no &quot;document&quot; on the side of the server any more. The document is assembled dynamically for each browser visit, often implying Javascript and asynchronous techniques. To deal with these aspects takes some time, of course. Searching the WWW intelligently means that dozens, if not hundreds of documents have to be visited and inspected in a continuous manner. </p>
      <p>The answer to these challenges is a completely new paradigm for browsing the web, just that offered by iTexx.</p>
